Peer led focus groups, a qualitative social science research method, and their use with young people are examined. The paper outlines three developments that have contributed to their emergence, namely: traditional focus groups, peer education and participatory research. Drawing on a study in progress, the advantages and challenges associated with peer led focus groups are discussed. A key benefit is that the power differential between the adult researcher and the researched is removed, at least at the point of data collection, rendering peer led focus groups one of few research contexts in which young people can speak collectively with no adult present. 相似文献

SUMMARY: It has long been accepted that adopted children need access to information about their origins in order to provide a satisfactory answer to the question ‘who am I?’. Such information is seen as vitally important to the formation of a clear and positive sense of identity in adulthood. This study examines the role that such information plays in the formation of personal identity and analyses accounts from 67 adopters of their children's requests for information about their families of origin. Comparisons are made between adopters whose children maintain contact with their families of origin and those whose children have no contact. 相似文献

Attitudes and Values of Scottish Farmers: “Yeoman” and “Entrepreneur” as Factors,Not Distinct Types1
Elisabeth J. Austin Ian J. Deary Gavin J. Gibson Murray J. McGregor J. Barry Dent 《Rural sociology》1996,61(3):464-474
Abstract We investigate the validity of the classification of farmers into two or more distinct types on the basis of attitudes, objectives, and values. Factor analysis of data from a survey of farm pluriactivity in Scotland (N=472) shows that attributes ascribed to “yeoman” and “entrepreneur” types emerge as separate factors rather than as a single bipolar factor. No clustering of the factor scores corresponding to distinct types is found. We also present correlations of the factor scores with attitudes to on- and off-farm pluriactivity and with observables such as age and off-farm employment. The desirability of analyzing survey data by methods which do not make assumptions about typology is discussed. 相似文献

This study examined ethnicity and psychological predictors of beliefs in guilt and innocence in the O. J. Simpson trial. A mixed-gender, multiethnic sample of 441 college students completed measures examining trial beliefs, trial-related attitudes, ethnic identification, pro- and anti-Black attitudes, and authoritarian personality traits. Results revealed that: (1) mean differences existed among ethnic groups on all variables examined; (2) proximal attitudes mediated relations between psychological characteristics and trial outcome beliefs; and (3) specific relations depended (to some extent) on ethnic group membership. Differences within and between ethnic groups may reflect schematic differences due to differential experiences with societal institutions, identification with (or rejection of) mainstream values, and race relations in American society. 相似文献

This paper describes an EM algorithm for maximum likelihood estimation in generalized linear models (GLMs) with continuous measurement error in the explanatory variables. The algorithm is an adaptation of that for nonparametric maximum likelihood (NPML) estimation in overdispersed GLMs described in Aitkin (Statistics and Computing 6: 251–262, 1996). The measurement error distribution can be of any specified form, though the implementation described assumes normal measurement error. Neither the reliability nor the distribution of the true score of the variables with measurement error has to be known, nor are instrumental variables or replication required.Standard errors can be obtained by omitting individual variables from the model, as in Aitkin (1996).Several examples are given, of normal and Bernoulli response variables. 相似文献

There has been a general absence of research to explain why personnel policies develop in organizations. This article has two objectives: (a) development of a theoretically relevant scheme for clustering personnel policies for analytic purposes, and (b) presentation of an explanatory model suggesting how contextual influences shape these policies. 相似文献

The purpose of this study was to validate Hanson's Learning Profile Inventory (LPI) and Teaching Style Inventory (TSI) further, and to assess the degree to which self-reported style preferences on these scales corresponded to actual observable learning and teaching style behaviors of students and teachers in differing instructional situations. No significant differences were found between the reported and observed learning and teaching style preferences of students and their instructors. Further, student and teacher classifications on the GEFT test of field independence/dependence corresponded to their classifications on the introversion/extroversion scale of the LPI and TSI further clarifying and validating this component of this scale on these two measures. This study was a formative study with a small sample (N=12) due to the burdens of observational ratings, which needs to be replicated with a confirmatory study. 相似文献

The workers' compensation system was established to provide fair access to compensation for workers who have experienced occupational injury and can no longer work. It was expected that such a system would reduce individual legal claims. Evidence indicates that many injured workers proceed with a variety of appeals indicating dissatisfaction with the current system. The fishing industry is extremely dangerous. The aim of this research was to explore the experience of injured fish harvesters who were making use of a compensation system. Interviews were held with a sample of injured in-shore and deep-sea fish harvesters. In general, they identified themselves strongly as hard-working people who did not deserve their injury. They also reported substantial frustration with the staff of the compensation system who they believed treated them with suspicion and disrespect. The deep-sea fish harvesters were more concerned with the amount of compensation. This dissatisfaction with the system contributed to the fish harvesters' use of the appeals procedure. The fish harvesters' complaints are discussed with reference to the concepts of distributive and procedural justice. 相似文献

Residential Air Exchange Rates in the United States: Empirical and Estimated Parametric Distributions by Season and Climatic Region 总被引:2,自引:0,他引:2
The purpose of this paper is to undertake a statistical analysis to specify empirical distributions and to estimate univariate parametric probability distributions for air exchange rates for residential structures in the United States. To achieve this goal, we used data compiled by the Brookhaven National Laboratory using a method known as the perfluorocarbon tracer (PFT) technique. While these data are not fully representative of all areas of the country or all housing types, they are judged to be by far the best available. The analysis is characterized by four key points: the use of data for 2,844 households; a four-region breakdown based on heating degree days, a best available measure of climatic factors affecting air exchange rates; estimation of lognormal distributions as well as provision of empirical (frequency) distributions; and provision of these distributions for all of the data, for the data segmented by the four regions, for the data segmented by the four seasons, and for the data segmented by a 16 region by season breakdown. Except in a few cases, primarily for small sample sizes, air exchange rates were found to be well fit by lognormal distributions (adjusted R2 0.95). The empirical or lognormal distributions may be used in indoor air models or as input variables for probabilistic human health risk assessments. 相似文献
